Wet lens adapter option for Aquatica housings?

I would like to know what other Aquatica users are doing to add wetlens to their setups. Unfortunately the Aquatica macro ports do not have a 67mm threads and some form of adapter is required at this point.

I have looked at the Subsee Adapter (http://reefnet.ca/products/subsee/) but the quoted price of $300 just for the adapter looks a little steep.

I also read Adam Hanlon's recent review of the Dyron Adapter and it looks like it does the job for the cost of $100. Unfortunately Dyron doesnt make an adapter as yet for the Aquatica Macro port.

Is there any other adapters which accept 67mm threaded wetlens for the Aquatica macro ports?

Regards Mark

I recieved an email from Dyron stating that they are in the porcess of making an Adapter for Aquatica and should on the market by the ned of the year.
